NEW IN PARIS The Doosan Portable Power display at the Intermat 2015 Exhibition will include a number of important new products being launched at the show. They include redesigned and Stage IIIA compliant G40-IIIA and

G60-IIIA generators, alongside several new portable compressors including the Stage IIIA compliant 7/53, Stage IV compliant 12/154 and 12/254 and 7/125-10/110 Stage IIIB Dual Mode models.

New generator platform Providing 40 kVA and 60 kVA prime power, respectively, the G40-IIIA and G60-IIIA models are part of the new platform of generators from Doosan and share a common design with the G80-IIIA to G200- IIIA models launched over the last two years. The Yanmar-powered G40-IIIA and John Deere-powered G60-IIIA generators will both be available with electronic speed regulation (optional on the G60-IIIA model) providing, in addition to stability and better load take-over capabilities, a flexible dual frequency 50/60Hz working mode (optional for both models). New stage IIIA portable compressor The new 7/53 portable compressor is a 36 kW Stage IIIA compliant replacement for the 7/51 model and has been redesigned to allow Doosan to keep this model in the Stage IIIA category, avoiding the need to transition to meet Stage IIIB regulations. The new features on the 7/53 portable compressor include forklift slots and a new bunded base option. The 7/53 compressor has an intuitive,

abrasive blasting, spray painting and optical fibre blowing. Also meeting Stage IV emission stand- ards, the new 12/254 compressor is powered by the 247 kW Cummins QSL9 diesel engine meeting the regulations without the need for a DPF. The 12/254 model again offers both compact size and easy serviceability for added value performance. New ‘dual node’ feature The 7/125-10/110 Stage IIIB model has a new ‘Dual Mode’ feature as standard, with a choice of two pressure and flow ratings on the same machine. By pushing a button on the keypad, the operator can switch between ‘LO’ and ‘HI’. This ‘two-for-one’ solution replaces the need to choose between different models as used to happen in the past and offers much greater opera- tional flexibility from the same machine. The new 7/125-10/110 portable compressor is powered by the Stage IIIB Cummins QSB 4.5 water-cooled diesel engine providing 97 kW of power and meeting emis- sion regulations through the use of cooled exhaust gas recirculation (EGR) and diesel oxidation catalyst (DOC) after-treatment technologies, without the need for a DPF.

simple key-start sequence, ideal for rental companies because of the reduced risk of machine abuse by untrained operators. The user-friendly control panel offers an open layout of instruments and warning indicators. A folding lift bail reduces the risk of theft by keeping the lifting eye within the compressor enclosure. A built-in toolbox compartment offers ample storage space. New stage IV compliant portable compressors The largest single axle model from Doosan, the new 12/154 compressor is the Stage IV successor to the previous 12/150 model and is again powered by the Cummins QSB6.7 6-cylinder diesel engine and meets Stage IV regulations without the need for a diesel particulate filter (DPF). Compact in size, the 12/154 offers excel- lent towing stability. It is intended for appli- cations in plant hire, construction, quarrying and general industry. This encompasses not only standard compressed air applications such as powering breakers and tools in road repair, demolition and refurbishment, but also more specialist uses such as drilling,
